Fatented May 1, 1934 airs STAiEd PATENT OFFEQE 4 Claims.

The present invention relates to basket-making machines; and an object thereof is to provide in such a machine improved means for fastening the hoops on the basket; and further, to provide improved means for holding the hoops on the basket while the same are being fastened together; and further, to provide improved means for lessening friction between relatively movable parts of the machine.

These and any other and more specific objects are attained by, and the invention finds preferable embodiment in, the illustrative machine particularly described in the body of this specification and shown by the accompanying drawings,

' in which:

Figure 1 is an elevational front view of a basket-making machine;

Figure 2 is an elevational front view of portions thereof (enlarged) showing the parts in another position;

Figure 3 is an axially sectional view of a portion of the concave form of the machine taken on a vertical plane corresponding to line 33 of Figure 4;

Figure 4 is an end or face view of said portion, shown partially in transaxial section taken on a plane corresponding to line 44 of Figure 3;

Figure 5 is a top plan view of said portion of the concave form;

Figure 6 is an axially sectional view of said portion of said form and an elevational side view of a portion of the cooperating convex form of the machine with the basket-making material between said forms;

Figure '7 is an end or face view of a portion of said concave form showing a modified construction thereof;

Figure 8 is an elevational side View of portions of said forms with said material between them, the concave form being partially sectioned axial- 1y on line 88 of Figure 7; and

Figure 9 is an axially sectional View of parts similar to Figure 6 but illustrating a modified construction thereof.

In Figure 1 is illustrated a basket-making machine of the type shown in Patent No. 619,182 to William Jackson and in Patent No. 1,848,897 to Bayard T. McAlvay.

In this machine a convex circular form 1 is rotatable in a bearing 2 on the standard 3 of a carriage 4 slidable in a way 5 on the base frame 6, being thus rotated by the shaft '1 on which this form is splined. A concave form designated generally 8 is slidable, coaxialiy with said shaft, on the standard 9 of the base frame, from the position seen in Figure 1 to that shown in Figures 2, 6, 8 and 9 in which movement the basket-making mat 10, formed of radially extending thin strips or staves 11 connected in their middles and positioned on the support 12, is bent over the end of the convex form and held against its circular side by the concave form, as shown in Figures 2, 6, 8 and 9. As the convex form intermittently stops in its step by step rotation (in which rotation it rotates the basket-making material with it), hoops 13, 14 are secured to the staves 11 by suitable fasteners or staples driven therethrough and clinched on the anvil rings 15, 16 of form 1 by suitable fastening means having vertically operating hammer ends 17, 17.

So far as above described, this machine is well known and its parts may be operated in proper sequence by suitable and well known means, some of such means, as are shown in said McAlvay patent, being indicated in these drawings; and the hoops 13, 14 may be formed of strips fed to the machine and thereby bent into hoop form in the manner described in said McAlvay patent.

The present invention is found in the concave form 8 and its relation to the hammer 17 of the fastening means. This form 8 has at its end a circular peripheral rim member or ring 18 which in the approaching movement of the forms engages the staves 11 and bends them over the end of the convex form and presses them on its circular side, with the hoop 13, as shown in some of the views, between the staves and said rims inner surface, and in the turning movement of the convex form smooths out the basket-making material comprising the staves and said hoop.

The rim member or ring 18 has a gap 19 through its upper side, aligned or registering with the hammer 1'7, so that said hammer in its operation passes through this gap to drive the staples through the staves or through the hoop and staves as shown in Figures 5 and 8 when the forms 1 and 8 are in the relative position shown in Figures 2, 6, 8 and 9. Thus, the hoop 13 as shown in Figures 6 and 8 while being secured to the staves is snugly held in contact therewith by said rim or ring.

In order that the rotation of form 1 may carry the basket-making material (mat and hoop) freely with it, this rim 18 is desirably provided, as shown in Figures 3, 4, 6 and 9 with anti-friction devices, as the rollers 20 whose end spindles 21 turn in bearings 22 in the circular channel 23 of the annular member 24, and in the bearings 25 in the flat ring 26 detachably secured as by screws 27 on the end of the concave form and covering said member 24 and holding it in the recess 28 of form 8.

As shown in Figure 8, the roller bearings are Omitted, the smooth inner surface of the annular member 24' bearing directly on the basket parts. Said member is desirably of hardened metal and has a gap 33 registering with gap 19.

A circular disk 29 on which the bottom 30 of the basket being formed is clamped by the end of form 1, and rotating therewith about the spindle 31, desirably has anti-friction ball bearings 32.

As shown in Figure 9, the basket-making material comprises a hoop 14 near the bottom of the basket and spaced slightly above said bottom, the staves being bent in a slight curve at 33, and the roller bearings being above this hoop and bearing directly on the staves 11 which are fastened together by fastening means or hammer end extending through the gap 19 in the rim or ring 18.

The invention being intended to be pointed out in the claims, is not to be limited to or by details of construction of any particular embodiment thereof illustrated by the drawings or hereinbefore described.

I claim:

1. In a basket making machine: coaxial basket forms convex and concave respectively and relatively movable axially and turnably in basket forming cooperation, the convex form carrying the basket-making material turnably therewith and the concave form including a non-rotatable circular member containing a removable coaxial annular member provided with anti-friction rolls and having also a ring detachably secured to the end of the concave form and extending over said annular member for holding the same in place, said rolls bearing on said material in the relative turning movement of the forms and pressing the same on the side of the convex form, said members and ring having a gap extending from the end of the concave form; means extensible through said gap for fastening the parts of said material together in basket form.

2. In a basket making machine: coaxial basket forms convex and concave respectively and relatively movable axially and turnably in basket forming cooperation, the convex form carrying turnably therewith the basket-making material comprising staves bent thereover and a hoop surrounding the same and the concave form including a non-rotatable circular member containing a removable coaxial annular member provided with anti-friction rollers and having also a ring detachably secured to the end of the concave form and extending over said annular member for holding the same in place, said annular member having bearings in which the rollers turn, said rollers bearing at their sides on said hoop in the relative turning movement of the forms and pressing said material on the side of the convex form at the opposite sides of a gap extending through said members; means extensible through said gap in the stationary position of the forms for fastening said hoop on the staves.

3. In a basket making machine: coaxial basket forms convex and concave respectively and relatively movable axially and turnably in basket forming cooperation, the convex form carrying the basket-making material turnably therewith comprising staves bent thereover and a hoop surrounding the same adjacent the bottom of the basket formed of said material, and the concave form including a circular side portion and a circular member within the same bearing on said hoop in the relative turning movement of the forms and pressing said material on the side of the convex form, said side portion and said member being concentric with the axis of both forms and having a gap extending from the open outer ends of said portion and said member; means adapted to pass into said gap in the relative axial movement of the forms for fastening said hoop on the staves within said open outer ends.

4. In a basket making machine: coaxial basket forms convex and concave respectively and relatively movable axially and turnably in basket forming cooperation, the convex form carrying the basket-making material turnably therewith, and the concave form including a circular side portion and a circular member within said side portion provided with anti-friction rolls bearing at the opposite sides of the hereinafter mentioned gap on said material in the relative turning movement of the forms and pressing said material on the side of the convex form, said side portion and said member being concentric with the axis of both forms and having a gap extending from the open outer ends of said portion and said member; means adapted to pass into said gap in the relative axial movement of the forms for fastening together those parts of said material which lie within said open outer ends.
